Caracterización geotécnica y modelamiento geomorfológico de la evolución de un movimiento de ladera: Estudio de caso Belén

Abstract

Abstract: The development of this study focused on understanding the behavior and evolution of the displacement present on a slope located in the Belén sector. Therefore, various soil characterization tests were carried out, including granulometric analysis, determination of plastic limits, and direct shear tests, which allowed defining the nature of the material and obtaining fundamental parameters such as strength, unit weight, and angle of friction. The information collected served as the basis for constructing the geotechnical model in the GEO5 software, integrating the actual terrain profile and site-specific aspects, such as the depth of the main crack, the loads induced by the road, and the corresponding seismic parameters. Using the stability analysis methods employed in the program, such as Bishop, Fellenius, Spencer, Janbu, and Morgentern-Price, it was determined that the slope does not reach the minimum expected safety levels, since the safety factors obtained are below acceptable limits. This confirms that the hillside is in a state of instability that requires technical attention.
